Smoke grenades??

I was looking around on the internet today, and found out at www.smokegrenades.us that although you may need an AFT explosive license to order an actual M-18 smoke grenade, that you don't need one to order a comparable Fat Man II pull pin smoke grenade, or a colored smoke device that requires lighting.

Two questions immediately come to mind:

1.) Would it be worth the money to buy a few smoke emitting devices for disaster preparedness purposes?

2.) Does smoke have any tactical value for me as a private individual? What about in an extreme natual disaster/loss of services situation?

They're fun to play with at paintball games or whatever, but otherwise I wouldn't bother with one. Possible exception: an orange Coast Guard approved type as a means to signal an aircraft if you're lost in the woods or something. Even then, you're probably better off with a mirror.

That site actually sells those orange things.

Well, after reading all the posts on this thread, maybe I'll get one of those things IF I get more into desert exploration and am concerned with getting lost in the desert.
